How To Fix An Overheating Power Supply

The Power Supply Unit of your pc is designed to function inside sure temperature limits. So if the temperature goes too excessive, it may make your system unstable, leading to undesirable freezes and crashes.

It is, subsequently, important to take care of overheating to take care of the system’s efficiency and keep away from harm to the PC parts.

In this text, I’m going to speak in regards to the methods to resolve the PSU overheating downside. Starting from primary fixes like cleansing out mud and checking the airflow, I’ll transfer to superior fixes like checking the ability requirement and tweaking the overclocking settings.

Let’s dive straight into them.

Check the Power Supply Temperature

Before concluding that your energy provide is overheating, it’s very important to find out whether it is truly overheating. Let’s first begin by checking the PSU temperature.

Since there aren’t any software program purposes that allow you to do it, it’s important to use instruments like an infrared thermometer or thermal imaging cameras.

Here’s what I discovered after I measured the temperature on my Corsair RM 850x with my infrared thermometer. 66.5°C!

The PSU usually operates between the inner temperature of 40°C to 60°C. But there are additionally some high-spec PSUs that may function as much as a whopping 80°C-90°C, at the price of lowered effectivity. Having stated that, it’s not regular for a PSU to go above 60°C. You can think about it as overheating.

Moving ahead, you can too gently place your hand on the outside or on the air exhaust vent of the PSU and really feel it for a second. If the floor is uncomfortably sizzling to the touch for an prolonged interval, this additionally signifies overheating.

Do notice that poor air flow is without doubt one of the main causes for overheating. So, to start with, confirm that there aren’t any obstructions across the PSU vents which are presumably blocking the airflow. If your room temperature is simply too excessive, chances are you’ll want followers or air conditioners.

Inspect the PSU Fan

High-end PSUs as of late embody a hybrid fan mode, the place the PSU fan stays off or spins at low speeds till a selected temperature or load threshold is reached.

However, when it begins rotating, you must ensure that it’s doing its job appropriately. If it doesn’t spin at its full velocity even when overheating, search skilled assist to repair it.

Below you possibly can see the temperature-fanRPM curve for my EVGA Supernova 550 G3 PSU. You can see how the RPM (rotations per minute) tends to extend with rising temperature.

Fix PSU Orientation and Improve Cooling

Coming to the PSU orientation, many of the PC circumstances at the moment are designed to mount the PSU on the backside dealing with the fan draw back.

But in case you have poor air flow on the backside, you can too flip the PSU such that the fan faces upwards.

Having stated that, you also needs to ensure that your system has a correct cooling mechanism. Otherwise, the PSU fan will consumption sizzling air from the PC case itself, additional rising its temperature.

You can settle down your PSU by enhancing the general cooling of the system. Depending in your PC case, you might both set up more followers or exchange the present ones with high-quality followers. You also can make your case followers spin sooner from the BIOS or using manufacturer-specific software program.

Clean the Power Supply Unit

If your PC has been left unattended for a very long time or is being utilized in a dusty setting, there are probabilities that the PSU followers and vents have been clogged with mud and particles.

You might also expertise buzzing or clicking noises from the PSU in such circumstances. It clearly signifies it’s time so that you can get the mud off the PSU.

When it involves cleansing the PSU, you should be very cautious in regards to the potential hazards of improper cleansing. It could make the mud, dust, cobwebs, and so forth., caught on the PSU fan and physique to choose the PCB, which is able to later push it in the direction of thermal throttling.

Here’s a fast information on how one can clear the ability provide unit of your pc. If you suppose you will have a fairly dusty PC, I additionally counsel you clear your pc.

Manage Cable Clutters

Most of the time, if you’re using a non-modular PSU, you should have pointless cables tangling contained in the PC case. It can typically prohibit the airflow in your system.

To counter the issue, it’s essential bind these pointless cables correctly and enhance the cable routing. Only then you possibly can create a greater room for airflow.

When it involves cable administration inside your PC case, the modular and semi-modular PSUs all the time win the race. So, I like to recommend you employ any of those as a substitute of the non-modular ones.

Furthermore, you must all the time use the real energy provide cables that come bundled with the PSU. If you’re using substandard cables along with your PSU, it may fail to ship increased energy for the PC upon its requirement, which may result in overheating.

Check the Power Requirement

Next, you must all the time make it possible for the rated output energy of your PSU is increased than the ability requirement of your system. At least 25%.

If the ability draw is near the PSU’s capability, it struggles to fulfill the calls for and begins overheating. Let me rapidly share my expertise relating to this.

Years back, I had a 650W PSU that was working fairly properly till the day I put in the RTX 3080 Ti GPU. Since then I began dealing with PSU overheating points and frequent system restarts. I later realized that the 650W was not sufficient for my setup, and I needed to improve to an 850W PSU.

You also can rapidly calculate the ability requirement of your system using any on-line energy provide calculator and get one which most closely fits your wants.

Note: GPUs from RTX 3000 collection are additionally reported to have momentary energy spikes. If you’re going by means of an identical scenario, I counsel you get an ATX 3.0 commonplace PSU that may take care of such transient spikes. Some ATX 3.0 licensed PSUs are the HELA 1300R from SilverStone and SuperNOVA 850G XC from EVGA.

Disable Overclocking

Whenever you overclock your device, be it a CPU, GPU, or RAM,  it attracts more energy than within the standard situations. As such, if the PSU fails to fulfill the ability requirement, it begins overheating.

Not solely does it overheat, it may typically trigger Blue Screen of Death (BSOD) errors too. I as soon as occurred to overclock my CPU in a low-wattage PSU setup that triggered the CLOCK_WATCHDOG_TIMEOUT error and crashed my PC.

To counter this downside, chances are you’ll both disable the overclock settings or improve your PSU, whichever fits your wants.

Repair or Replace the PSU

As the PSU ages, its inner parts put on down, resulting in lowered effectivity and elevated warmth era. So, if nothing appears to work, possibly it’s time to restore or exchange your PSU.

Kindly go to a licensed restore middle to get your PSU repaired. Attempting to disassemble the PSU your self can void any remaining guarantee and likewise poses critical threat of shock hazards.

You can clearly see a message in your PSU mentioning to not take away the PSU cowl. Here’s what the message seems like on my EVGA SuperNova 550 G3.

If the PSU is irreparable, think about getting a brand new one. While selecting a PSU, all the time accept one which has a better energy provide effectivity. The more the effectivity is, the lesser warmth it is going to dissipate.
